Normal pressure hydrocephalus: Did publications alter management?

Forty six Dutch neurologists and neurosurgeons were interviewed to evaluate the clinical value of research articles on normal pressure hydrocephalus (NPH). From this survey it appears that most clinicians still limit investigations to psychometry, CSF-tap test(s), and cisternography. The main reasons for not using other techniques were: their invasiveness, technical complexity, poor availability, lack of time and doubt on their additional predictive value. There is an obvious discrepancy between the quantity of publications on NPH and their impact and their ability to assist clinicians in selecting potential NPH patients for a shunt.
